Valor G4 Gas Insert, Natural Gas


If your fireplace opening is on the large side, the Valor G4 is built for it. Valor designed this insert to fit existing large fireplace openings, and the 28 by 18 inch window gives you 504 square inches of fire to look at. Choose birch, driftwood, or traditional logs on the stainless steel burner, then a liner and front to finish it.

This 780RN runs on natural gas with an input range of 14,000 to 28,000 Btu/h. AutoFire and the Valor 10 remote come with the engine, and the 780R engines do not support Valor 10 WiFi. Because it runs on battery power, it doesn't need household electricity to operate as a heater. The fuel bed, liner, front, and backing plate are separate purchases.

Why Homeowners Choose the G4

  • Sized for big fireplaces. It's designed for existing large openings, so the fire fills the space in proportion.
  • A 504 square inch fire view. The 28 by 18 inch window is the centerpiece of the whole installation.
  • Battery powered. Battery operation means it doesn't need household electricity to run as a heater.
  • Finish it your way. Three log sets, several liners, and a range of fronts and backing plates.

This listing is the Valor 780RN engine, the current G4 stainless burner direct vent gas insert for natural gas. The fuel bed, liner, front, and backing plate are sold separately.
